To all whom it may concern.-

Be it known that I, WILLIAM W. SHOE, of Philadelphia, Pennsylvania, haveinvented a new and useful. Improvement in Devices for following is aspecification:

The object of my invention is to construct a light and compact buteffective steering and propelling device, adapted especially for smallboats, canal boats, lighters, &c., an object which I attain in thefollowing manner, reference being had to the accompanying drawing,

Figure 1 is a side view, partly in section, of my improved steering andpropelling device; and :Fig; 2, a transverse section;

The rudder-post is made in two parts, A and A, connected togetherby'means of side plates at, which can slide on and are guided by 'eachother, so that the lower part A of the post can manner as an ordinaryrudder. Each of the pintles b is carried by a sleeve, (1, whichemtically thereon, the upper sleeve being secured after adjustment bymeans of a set-screw or otherwise, and the lower one by means of acam-lever, d, hung to the sleeve, and extenderated from the boat. Theupper end of the adapted the tapering end of the tiller B, which may beseouredin position by means of a pin,

in'g-pulley, D, theshaft of which is furnished with crank-handles, to beoperated by the 00 from the driving-pulley D to a pulley, E, on the-topof the shaft F by means of the belt f,

The shaft F is made in twoparts, the upper of which has its bearing in abracket, g, projecting from the upper portion A! of the rudderitsbearing in a frame, G, carried by the lower portion A of said post, theupper end of the said lower portion of the shaft F being of a square orangular section, and being adapted to the similarly-shaped interior of-a sleeve, h, secured to the lower end of the upper portion Theparticular construction of the propeller need not be described here, asit will form the subject of a separate application for a patent.

To the rear of the frame G is secured a plate,

P, which serves to aid thepropeller J in steer ing the boat whenthe-frame G is turned'to one side or the other.

The pintles b b are made adjustablevertically, in order that the devicemay be applied to boats having eyes at different distances apart, theupper pintle being first adjusted to the upper' eye, and the sleevecarrying the lower pintle being then released from the post A, by movingthe cam-lever d in the direction of the arrow, Fig. 2, after which thesleeve is adjusted vertically to the desired position, and again securedby restoring the said lever d to its former position. I

The object of making the postA and shaft F in two parts, and connectingthe parts of the post by the sliding plates at and the parts of theshaft by the sleeve h, is to permit the lower portion A of the post Aand the frame Gr carried by the same to be adjusted vertically, so thatthe propeller J shall always be properly submerged Whether the boat belight or loaded.

By the use of the plates at, also, a space is provided between. the samefor the reception of the bolt with which the stern of the boat isgenerally provided, and by which-it is suspended from the davits.Moreover, the plates, by coming in contact with the sides of thestern-post, prevent undue movement in either direction of the post A andthe propellerwheel.

The raising and lowering of the lower portion A of the post A and theparts carried by the same may be readily effected from on board the boatby means of a cord or chain, y, and pulleys v v, the upper end of thecord being secured by passing it round a suitable cleat.

' compact packing of the device for storage or transportation.

Y The post A and its connections being removable from the boat, thedevice is not subjected to the risk of being damaged when the boat isnot in use, or is lifted out of the water. Furthermore, it does notprevent the use of the ordinary rudder when it is desirable to propelthe boat by sail or oars.

- I do not desire to confine myself to the beltand-pulley mechanismshown and described for operating the shaft F, as bevel-gear or anarrangement of levers might be substituted for the same in some cases.The pulleys and belt, however, are to be preferred.

, I claim as my inventi 0n 1. The combination of the propeller-wheel J,shaft F, and intervening gears with the post A, hung to pintles on thestern-post of a boat, so as to be readily turned on or removedtherefrom, all substantially as and for the purpose set forth.

2. The combination of the pot carrying the propeller-wheel and shaft F,with the tillerarm B, carrying the driving appliances, all substantiallyas specified.

3. The combination of the post A, carrying the wheel J and shaft F, withthe tiller-arm 13, carrying the device to which the power is applied,and rendered detachable from the post A, as specified. Y

4. The combination of the wheel. J and its driving mechanism, the postA, and shaft F, each made in two parts, connected together so as topermit vertical adjustment of the lower part in respect to the upperpart, and a device, substantially as described, for retaining said lowerpart in the position to which itmay be adjusted.

5. The combination of the upper and lower portions A and A of the post Awith the side plates a, serving to connect the two partstogether, allsubstantially as described.

6. The combination of the post A with sleeves d, carrying pintles b, andcapable of being adjusted vertically on said post A, as set forth.-

7. The combination of the post A with the lower sleeve d and itscam-lever d, as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
